White blood cells are identified by their size, the shape of the nucleus, the proportion of the cell that is taken up by the nucleus, and the amount of granules in the cytoplasm. The pale pink cells without nuclei in all of the images are red blood cells. The dark purple structures in the cells are the nuclei. Granules can be dark purple (like in the basophils) or dark pink (like in eosinophils).
